I just received my Book Port, a few days, ago. Since the new version will be able to read the digital NLS files, should I return my Book Port and wait for the new version or is there going to be someway to listen to the NLS digital files on the old version? Since I just got mine, I don't want to have purchased the wrong one. Also, is their a key on current Book Port that tells you what the commands are? I don't like carrying around the reference sheet with me because I am afraid that I might lose it. Will the new Book Port have this help feature. When will the new model be released. Barbara
